Hi all: I am a retired engineer who spent many years developing software for various non-real time applications. I am interested in continuing to develop software in a MacOS/iOS environment, primarily to support some of my hobbies, but do not know the best approach for doing so. At least initially, I would like to develop a few small applications that could run on a Mac or iPad for personal use (i.e., I am not interested in releasing the applications on the Apple Store - I only want to install the applications on my own devices). Does Xcode make sense as a development environment for me? Would I need to become a member of the Apple Developer Program?
